SST and Chl-a Regional Summaries
September 03, 2021
Below are monthly time series of mean sea surface temperature (SST, \(^\circ\)C) and chlorophyll-a concentration (Chla, mg m-3) for regions and stations of interest, including Marine Protected Areas. Click on the tabs to view plots.
The SST is a 4km resolution product available from NOAA, covering late 1981 to 2020. The Chla is a 4km product available from the NASA Ocean Biology Processing Group covering 2003 to 2020.
Note that these plots are current to 2020-12-31.
The time series are coloured by season: winter (January, February, March), spring (April, May, June), summer (July, August, September), and autumn (October, November, December).

Oceanographic Regions (orange boundary):
- AOI: Offshore Pacific Area of Interest
- EHV: Endeavour Hydrothermal Vents Marine Protected Area
- GH: East (GHE), Offshore (GHO), South (GHS), West (GHW) Gwaii Haanas National Marine Conservation Area Reserve
- SI: Scott Islands marine National Wildlife Area
- SK-B: SGaan Kinghlas-Bowie Seamount Marine Protected Area
- SR: Central (SRC), North (SRN), South (SRS) Hecate Strait/Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area
Selected standard oceanographic stations used for further calculations are shown as yellow points (stations GI02, Mason53, P4). The statistics used are from a 5x5 pixel box centered at the station coordinates.

Climatology Plots
This is just a placeholder at the moment. Thinking similar to the buoy plots on the marine heatwave page.

This is also a placeholder, with some of the plots I updated in 2020.
